Do you have to connect a power supply to the 5v input? If so, how many amps are needed?

No. It gets its power supply from the raspberry itself. No need for external power

No you do not - simply connect it to the GPIO headers on a raspberry pi. The connector on the bottom is where the unit draws power from.

I don't have any info on amps - the power supply is 115V/60Hz. I didn't have to purchase any special plug.

Power Supply rated @ INPUT: 100-240 @ 50/60Hz, 1.4 amps; OUTPUT: 12V @ 4 amps

I gave it to my computer guy. But I remember him saying I needed a new power supply to run it. Sorry I wasn't more help.

nope, highly recommended that you get 500-600 psu and connect it directly from the psu

It is plug and play. You don't need a power supply. Plug it in. And it should set up.

No power supply provided. It requires a 120V AC to 12 V DC transformer / driver. You will need to figure the amount of amperage required based on the number of running feet in order to purchase the correct transformer / driver for your particular application.

Hi, you don't need the ac power supply but I went with it ti have more power and I am glad I did, would do the same next time !

Not quite sure on the amperage but you'll need a separate 12V line from the PSU for the card (it has separate connector for this)

It does not come with a power supply. You have to buy that separate for another $20.

you need to add up all of your items in the computer to know what is needed. look at the original setup..it should have listed the power requirements for each item

I don't believe the -5V is necessary. It does not light up when I test a power supply See this article: http://pcsupport.about.com/od/insidethepc/a/atx-pinout-24-pin-12v-psu.htm Also, check the label on your PS to see if -5V is listed.

The only DC Input is one 12VDC. All run from this single Power input. I do not see or was a 5V lead provide.

No. If you use a rectifier you would have less than 12vdc. I am pretty sure you just need to buy a 12vdc power supply

It is a 50 amp supply and will provide that at 12 volts continually. Your amp needs 120 amps. Oh those specs imply big external capacitors to deliver 5000 watts. It can only take in 1440 watts (120 amps x 12 volts) and they don't create power.

The item is shipped without a power supply or any info regarding power supply requirements. I would have returned the one I bought, but, due to circumstances, I did not try to install the unit before the return period had expired. Sorry I can't be of more help, but I am stuck too.

In the specifications it lists the power requirements:* Input Voltage: 12VDC Power (max): 24W. This means you need a DC power supply that provides a maximum of 12 Volts DC and 24watts of power minimum. Several power supplies can be found on Amazon. So a 12 VDC, 25-30 watt power supply will work just fine.
